The patch titled Subject: ipc/msg.c: use list_for_each_entry_[safe] for list traversing has been removed from the -mm tree. Its filename was ipc-msgc-use-list_for_each_entry_-for-list-traversing.patch This patch was dropped because it was merged into mainline or a subsystem tree ------------------------------------------------------ From: Nikola Pajkovsky <npajkovs@xxxxxxxxxx> Subject: ipc/msg.c: use list_for_each_entry_[safe] for list traversing The ipc/msg.c code does its list operations by hand and it open-codes the accesses, instead of using for_each_entry_[safe].
